Same issue on Gentoo forums:
http://forums.gentoo.org/viewtopic-p-7329164.html

I had the same issue, and, additionally, X died after that (screen went blank and monitor cried "no signal").
dmesg: http://sprunge.us/AcOh

I would say that this version is beta due to http://googlechromereleases.blogspot.com/2013/06/beta-channel-update_19.html announce

Please test the following package (x86_64 only):

https://dev.archlinux.org/~foutrelis/chromium-test-pkgs/chromium-28.0.1500.52-0-x86_64.pkg.tar.xz

It includes a patch that disables the GPU sandbox which appears to cause a thread deadlock:

https://bugs.gentoo.org/show_bug.cgi?id=471198#c25

Yeah, that workaround patch seems to work.

However I still get core dumps it seems:

I still had problems with the test package above and with chromium-dev (29.0.1547.0-0), but executing with --disable-gpu-sandbox worked for me.

Please test 28.0.1500.71-1 from [extra].

I'm interested to know:

- whether the hangs are fixed (I included https://chromiumcodereview.appspot.com/18337010/ as a patch in the released package)
- if chrome://gpu indicates that hardware acceleration is working

Thanks.

No hangs as far as I can test it, have attached info below as you requested.

chrome://gpu output:

journalctl reports:

Jul 10 11:35:54 asus /etc/gdm/Xsession[466]: NVIDIA: could not open the device file /dev/nvidia0 (Operation not...ted).

So everything looks OK as far as I can see.

I'll wait for one more confirmation and then close this. :)

28.0.1500.71-1 works for me too. Before I could not browse Google+ or Youtube for a minute before it hung. Now it works. Thanks.
